` To all who/m. t mag/concern.'

Be it known that I, RYoIoHrNAiTo, a subject of the Empire of Japan, and resident in care of business department ot The Kanegauchi Boseki Kabushikil Kwaisha., Higashi-ShirieIke, Kobe, Japan, have invented `Certain new and useful Improvementsin De# vices for Preventing the Adhesion of Raw Silkat Reel Angles, of which the following isa specification. j i

My inventionY relates to vdevices for prefv venting silk thread from adhering to the reels and is especially adaptedior use in connection with silk reeling machines of the type reeling directly on the hank making swift. .f

According to the usual method of silk reeling the raw silk is wound vwhile in a wet` condition on the reel with the result that the thread adheres to thereel and also the layers kof silk stick together.'

LAccording to the present invention raw silk is passed through a tube before being wound on the reel and dry hot air is supplied to and `flows through the tube in a direction opposite to? `the vmovement of the silk whereby the latter is heated and its moisture `is evaporated. After through the tube, the rawsilk is again eX- posed to the atmosphere and is thus cooled and its sericin or silk gelatin is solidilied, and itis finall wound onthe reel.. Thus the adhesion o raw silkjto the reel is positively avoided. Y

The accompanying drawing illustrates an example of the deviceembodying the present invention. -F ig. l is a side elevation and Fig. 2 is a plan view of same. Inthe drawing (l) represents aKennel apparatus. Raw silk passes from said Kennel apparatus to the reel as in the known'reeling machines of the directreeling type. (3) represents hot air tubes of suitable size and length, connected Vwith a mainfpipe and positioned between the Kennel apparatus l and the reel 2, raw silk is-made to. pass through saidv tubes (5) is a hot 4air chamber connected withthe main pipev (4;) by

Within the heating' an elbow pipe (6), Y chamber (5) a suitablev heating means, for

instance steam pipe (7), is provided andk the air passing through said chamber is thereby heated to a desired temperature. A supply pipe (8) delivers air from a blower` 9 to the chamber i5.

passingr rlhe raw silk leaving the Kennel apparatus (l) Lpasses to the hot air tubes (3) in its moist state, Vand after passingthrough said tubes is exposed again to atmosphere, and then is wound on the reel f2., the air is supplied to the chamber (5) through the pipe (8)v by meansv of the blower (9),.and

The raw silk in its moist, state therefore,

, coming in close contact with the current ot hot air while passing through the tube (3), before being wound on the reel, is heated land rapidly" and thoroughly dried. The current of hot yair and the motion of raw silk being opposite to each other, the drying action is remarkably accelerated. Thus the raw silk is wound on the reel after having vbeen thoroughly dried, and consequent-lyv there is no danger of the silk adhering to the reel nor of the layers oi silk sticking together. The drying action of the heated air vhas no harmful effect on the silk but on the contrary improves the quality thereof. I claim f 1. Incombination with a silk reeling device, hollow members adapted toI receive silk thread during its passage to the reeling device, and means Ytor supplying heated air to said Vhollow members.

c 2. An arrangement as claimed in claim l characterized in that the hea-ted air is caused to travel through the hollow member in a direction opposite to the movement of the thread therethrough. Y

'3.15m arrangement as claimed infclaim l characterized in that the hollow member is larranged in spaced relation to the reeling device whereby the thread, subsequent to its passage through the hollow member passes for a distance through the atmosphere prior to its being wound upon the reeling device.

4. An arrangement as claimed in claim 1 characterized in that the hollow member is arranged in spaced Vrelation to the reeling device and that the heated air is caused to pass through the hollow member in a direction opposite to the movement of the thread therethrough.

5. In' an apparatus of the charatqtl desaid reeling device, a heating chamber eon- Vmain-pipe, air heating means located in said 15 nestedgwthhe' hollow member, an heating Clmmbelgrand means for supplying niv tothe 5 means located at Said elmmbelgjandmeans l`heritnffg''ehifnljl". Y
